Fair Access

Now that the sound and fury in the Open Access movement has quieted down a bit, we can revisit the arguments for open access. The basic question I would like to address is what ACM's stance should be with respect to open-access publishing models.

A Massively Parallel Adaptive Fast Multipole Method on Heterogeneous Architectures

We describe a parallel fast multipole method for highly nonuniform distributions of particles. We employ both distributed memory parallelism and shared memory parallelism to rapidly evaluate two-body nonoscillatory potentials in three dimensions on heterogeneous high performance computing architectures.
